It was announced today at San Diego Comic-Con that Michael Emerson has been cast in Arrow season 6. Emerson, known for his roles in Lost and Person of Interest, is said to be playing a mystery character according to EW.

It is rumored that Emerson will be portraying Helix leader Cayden James, who appeared last season with his head obscured. When EW recently asked executive producer Wendy Mericle whether Helix and Cayden James would return, here is what she said:

“You never know. They are still in the wind. We don’t like to leave those threads dangling.”

At Comic-Con, Mericle did reveal that Kacey Rohl would return as Alena, a Helix hacktivist. There will be multiple villains in season 6, which is something Emerson’s casting is hinting at. Executive producer Marc Guggenheim also discussed the multiple antagonists in an interview, saying:

“Season 5 was really about building up this team. By the end of the season, we had Team Arrow 2.0 in a really formidable tightly knit way. We wanted to really double down on this concept of family and found families. Toward that end, we started thinking of a group of villains, something we’ve never done on the show before.”

David Nykl is also set to return as Anatoly Knyazev, a member of the Bratva and former associate of Oliver Queen. Knyazev will also appear along with Richard Dragon, a name fans might recognize from the DC: Rebirth run of Green Arrow comics.

Manu Bennett is also set to return in the season premiere as the notorious Slade Wilson.

“After a violent shipwreck, billionaire playboy Oliver Queen (Stephen Amell) was missing and presumed dead for five years before being discovered alive on a remote island in the North China Sea. He returned home to Star City, bent on righting the wrongs done by his family and fighting injustice. As the Green Arrow, he protects his city with the help of former soldier John Diggle (David Ramsey), computer-science expert Felicity Smoak (Emily Bett Rickards), his vigilante-trained sister Thea Queen (Willa Holland), Deputy Mayor Quentin Lance (Paul Blackthorne), brilliant inventor Curtis Holt (Echo Kellum), and his new recruits, street-savvy Rene Ramirez (Rick Gonzalez) and meta-human Dinah Drake (Juliana Harkavy). Oliver has finally solidified and strengthened his crime-fighting team only to have it threatened when unexpected enemies from his past return to Star City, forcing Oliver to rethink his relationship with each member of his “family”
